内瘘穿刺速度对疼痛和穿刺成功率的影响

The impact of injection speed on the pain and the success rate of internal arteriovenous fistula

目的探讨不同穿刺速度对疼痛、动静脉内瘘穿刺成功率的影响。方法选择维持性血液透析患者80例,按穿刺速度不同随机分成实验组和对照组各40例。实验组患者行慢穿刺速度,从内瘘针针尖接触皮肤开始至停止进针止,穿刺速度为(1.48±0.39)s,动作轻柔,力度适中。对照组患者行传统快穿刺速度,从内瘘针针尖接触皮肤开始至停止进针止,穿刺速度为(0.77±0.26)s,动作较重,力度较大。结果慢穿刺速度在疼痛程度及内瘘穿刺失败率方面显著低于对照组,2组差异有显著性。结论慢穿刺速度能显著减轻患者疼痛,提高内瘘穿刺成功率。

Objective To discuss the impact of injection speed on the pain and the success rate of internal arteriovenous fistula. Methods Eighty enduring hemodialysis patients were chosen and evenly divided into experiment group and control group according to the injection speed. Patients of the experiment group were injected at a speed of （1.48± 0.39） s. The operation act was soft and the strength was moderate. The patients of the control group were injected at a speed of （0.77 ±0.26） s. The operation act was hard and the strength was powerful. Results Patients of the experiment group felt less painful than those of the control group and the success rate was higher than that of the control group. The difference of the two groups was significant （P〈0.01, P〈0. 05）. Conclusion To inject slowly clan ease the pain notably and raise the success rate.
